"We take our responsibility for providing safe and healthy learning environments in our schools seriously and are pleased to be able to share this information with the Miller-Driscoll community as well as the entire Wilton community," the district said in the statement.
The school board undertook a second round of testing to address concerns from parents about a review conducted last November by another independent firm, Cardno ATC, which had also shown Miller-Driscoll’s Indoor Air Quality levels met all state and federal standards.
The radon study of ground floor rooms was conducted in accordance with the recommended protocols of both the federal Environmental Protection Agency and the Connecticut Department of Public Health.
TRC Cos. Inc. said in its report to the district that "all radon sampling devices analyzed had results below the EPA/CTDPH recommended guidance level of 4 picocuries per liter (pCi/l) of air, with the highest reading in any room at 1.6 pCi/l," according to a report from the firm.
In addition to TRC’s finding that radon levels were well below the recommended action levels, TRC concluded indoor air levels met all state and federal guidelines.
TRC's industrial hygienists conducted a full investigation to determine what basic Indoor Air Quality levels existed in 121 locations in Miller-Driscoll. The survey consisted of visual inspections of the spaces coupled with baseline air sampling.
Baseline air sampling results for temperature, carbon monoxide, carbon dioxide, total particulates and relative humidity all were within recommended guidelines for schools. The microbial analysis results for indoor air samples were all within normal ranges for mold species found in the New England region for the time of year the testing occurred.
According to the Wilton Bulletin, however, some parents remain skeptical about the tests.
The TRC summary report can be found on the Miller-Driscoll website and on the Wilton Public Schools website.
